A novel approach to lean six sigma project management: a conceptual framework and empirical application

The recent evolution of Lean Six Sigma (LSS) presents a potent combination of the speed of Lean and the robustness of Six Sigma. Literature shows significant application of DMAIC (Define-Measure-Analyse-Improve-Control) framework in LSS projects. Many studies suggest that LSS makes a positive contribution towards the effectiveness of organisations. However, a few studies also suggest that organisations find DMAIC projects problematic, and in many cases ineffective. We investigate and resolve this paradox by conceptualising a novel LSS framework, and further test it for practical implications. A four-phase methodology is used. In phase-1, relevant data is pooled from multiple sources including the literature, semi-structured interviews and questionnaire-based survey in the scope of the manufacturing sector. The pooled data is classified and analysed in Phase-2. Phase-3 focused on development of the conceptual framework, and Phase-4 aimed to test the conceptual framework in select manufacturing firms in real-world environment. This study reveals focused gaps and shortcomings of the DMAIC framework for LSS project management. Secondly, we propose a novel approach to LSS project management by conceptualising ‘SDMMAICS’ framework. Thirdly, we validated the conceptual framework in real-world. Finally, the practical implications were discussed to add value to both researchers and practitioners.
